GEORGE C. WEISS, OF OAKLAND, CALIFORNIA.

MUSIC-LEAF TURNER.

Application filed July 20, 1914.

To all whom it may concern:

Be it known that I, GEORGE C. \Vniss. a citizen of the United States, residing at Oakland, in the county of Alameda and State'ofC-alifornia, have invented certain new and useful Improvements in Music- Leaf Turners, of which the following is a specification.

This invention relates to a music leaf turner and the principal object of the invention is to provide improved means for holding the leaf engaging members in a set position and for successively releasing the same when it is desired to turn the pages of a sheet of music.

Another object of the invention is to provide improved meansfor mounting the leaf engaging members and causing them to swing to a position to turn the page when desired.

Another object of the invention is to provide a music leaf turner of the portable type which may be placed on the music supporting shelf of a piano when in use.

This invention is il ustrated in the accompanying drawings, wherein Figure 1 is a view showing the improved music leaf turner in front elevation; Fig. 2 is a view of the music leaf turner shown partially in top plan and partially in section; Fig. 3 is a fragmentary sectional view of the music turner; Fig. at is a sectional view taken along the line -l l of Fig. 1; Fig. 5 is a sectional view taken along the line 55 of Fig. 1; Fig. 6 is a sectional view taken along the line 66 of Fig. 1.

The rack or frame 10 is rectangular in shape as shown in Fig. l and is provided with a lower flange 11 and an upper supporting plate or strip 12 upon which the music sheet or book is adapted to rest. The standard or shaft 13 extends from the upper bearing 14 through the supporting shelf 12 to the lower flange 11 and provides means for pivotally mounting the leaf turning arms.

The leaf turning arms which are numbered 15, 16, 17 and 18 are each provided with a bearing bracket 19 which is rotatably mounted upon the standard 13 and is provided with a cut out forming a housing 20 in which the spring 21 is positioned. This spring 21 has one end connected with the wall of the housing and has its opposite end connected with the standard as shown in Fig. 2 so that the spring will normally hold Specification of Letters Patent.

the arm upon the opposite side of the stand ard from that shown in Fig. 1. A bushing 22 is provided beneath the lower bracket 19 so that the leaf engaging arms will be held at the desired height to permit the clamps and finger 24 to engage the pages of a music book.

It is desired to releasably hold the arms in the position shown in Fig. l and therefore the mechanism shown in Figs. 1, 2 and has been provided. A catch 25 which is provided with arms 26 and 27 is rigidly mounted upon the actuating shaft 28 which is rotatably mounted in the bearings 29 and has its outer end portion bent to form a handle 30 terminating in a finger button 31. The bearings 29 extend upwardly from the free end portion of a leaf spring 32 which is secured to the flange 11. In order to hold the leaf spring in the position shown in Figs. 1 and 4: there is provided a lever 33 having a cam head 3% which extends beneath the free end of the leaf spring and raises the same when returned to the position shown in these figures. A spring 35 is placed about the pin 36 and engages the forks 37 extending from the catch 25, thus yieldably holding the catch in the normal position.

When this device is in use, it is placed upon the music supporting shelf of a piano and the music book or folder is placed upon the supporting shelf 12 with the pages which it is desired to turn engaged by the clips 23 and fingers 2 1. It is of course 0bvious that the fingers 2st will engage the inner faces of the pages which are to be turned thus preventing the page from being torn or dragged loose from the clips 23 when the arms turn. As soon as the page engaged by the arm 18 has been played, the finger button 31 will be pressed downwardly, thus moving the fingers 27 into engagement with the outer face of the arm 17 and moving the finger 26 out of engagement with the arm 18. The spring 21 of the arm 18 will then swing the arm to turn the page. After the page engaged by the arm 17 has been played, the button will be again pressed and process repeated. It is of course obvious that when the page has been turned, the button will be released and the spring 35 will return the catch to the normal position shown in Fig. 1 and move the finger 26 into engagement with the succeeding arm and move the finger 27 out of engagement with the same. After all of the pages have been turned, the cam lever 33 can be moved to permit the leaf spring to move downwardly. The arms can then be returned to the position shown in Fig. 1 and the cam lever turned to raise the free end of the leaf spring and bring the catch into engagement with the arm 18. In the drawings there has been shown four of these arms but it is obvio'us that any number can be provided.

I have therefore provided a music turner which is light and portable and which is very easy to operate. It will also be noted that this device is very simple in construction and will not readily get out of order and that it is so constructed that there is no danger of more than one of the turning arms being released at one time. It will also be noted that this device, is so constructed that when manufacturing the same that as many leaf turning arms as desired may be provided, the same releasing mechanism being used regardless of the number of turning arms.

What is claimed is A music leaf turner comprising a supporting frame, pivotally mounted leaf engaging arms yieldably held in a set position, a pivotally mounted catch provided with arm engaging fingers positioned out of alinement, means for yieldably holding said catch with one of said fingers engaging one of said arms and with the second finger positioned upon the opposite side of the arm and in front of an adjacent arm, and means for moving said catch to bring the second finger into a position to hold the second mentioned arm in a set position and the first finger in a position to release the first mentioned arm, said catch when returning to its normal position permitting the second arm to move into engagement with the first mentioned finger.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE C. WEISS.
